FIELD OF APPLICATION OF THE INVENTION

The present invention relates to a toy building set comprising at least one building element having a surface on which a number of coupling studs are arranged that extend from the surface, and wherein those coupling studs are configured in a pattern by which there is a mutually fixed distance between adjacent couplings studs, and wherein the toy building set further comprises a perforator, said perforator comprising a housing, wherein at least one punching tool is provided for punching material from a sheet element configured from a thin material, such as a sheet of eg paper, plastics or fabric, in such a manner that the perforator is capable of punching a hole in the sheet, which hole has such expanse that one or more coupling studs can be introduced into the punched hole.

The invention further relates to a perforator for use in connection with toy building sets comprising building elements with coupling studs.

STATE OF THE ART

Toy building sets comprising building elements or building blocks are known in many different configurations, and it applies to a large part of them that the individual building elements are provided with a number of coupling studs protruding from a surface on the building element to the effect that those coupling studs are capable of engaging with complementarily configured coupling studs on another building element, whereby the coupling studs on the one building element are received completely or partially in the complementary coupling means on the other building element.

Such toy building sets most often consisting of relatively hard and inflexible three-dimensional blocks and elements, the toy building sets are extremely suitable for building relatively massive structures that are to resemble buildings, machinery and other inorganic and immovable structures, whereas it is difficult, merely by use of the building elements of the toy building set, to construct light structures such as a wind shield for a toy patio, a banner on a building or a sail for a boat.

Thus, today toy building sets are known wherein the toy building set includes one or more sheet elements made of paper, plastics, foil, or some other sheet material, and wherein such sheet elements are, already by the manufacturer, punched into the shape it must have to enable use thereof in a specific context, and, also by the manufacturer, it is additionally provided with the holes it takes to mount the sheet element on the building element.

In the light of this, a perforator of the kind described above is known for use in connection with a toy building set as set forth above, which perforator is configured for punching a hole in a sheet of paper, foil, fabric or other sheet material, and wherein the hole which can be punched by means of the perforator is of such size that a coupling stud configured on one of the building elements of the toy building set can be introduced into the punched hole. Thereby it is possible to construct a structure consisting of a plurality of such building elements and to provide that structure with the sheet material which one has, on one's own, configured as a user of the toy building set.

It being thereby possible to punch holes where one desires to do so, which holes may subsequently be used for securing the sheet material to the erected structure by means of the coupling studs of the building elements, a much higher degree of freedom is achieved for adapting and designing sheet material elements in accordance with one's own wishes, and for subsequently providing the sheet material element with precisely the holes in those positions that are most convenient for enabling mounting thereof on a given building structure.

OBJECT OF THE INVENTION

Based on this, it is the object of the present invention to provide a toy building set with associated perforator, and a perforator by which it has been made even easier to shape a piece of fabric, paper or other sheet material in accordance with the shape one has imagined, said sheet being precisely provided with punched holes in the correct positions desired based on the use for which it is intended to fulfill in a given structure built by use of the building elements in the toy building set.

This is accomplished in that the perforator for the toy building set the housing comprises a substantially plane surface, wherein a number of indentations are provided that form a number of coupling means that are complementary relative to the coupling studs and are configured with the same mutually fixed distance as the distance between the coupling studs on the building element to the effect that the housing can be mounted on a building element.

In this manner it is enabled that the perforator can be mounted on a building element, following which the sheet can be introduced into the perforator with a view to punching of one or more holes in the sheet. If the user has thus built eg a given structure from a number of building elements and now wishes to mount a piece of fabric with a specific shape on that structure, the user can, by use of the perforator, mount or couple it onto the desired place on the structure built, and then punch holes in the sheet precisely where they need to be in order to enable mounting of the sheet in the same place on the structure.

Moreover, it is enabled that the manufacturer of the toy building set can draft instructions in advance as to how a user may him/herself produce various types of sheet elements, the building set as such functioning as a kind of boring template to the user, to the effect that the individual holes can easily be punched with a more accurate position than known so far.

According to a preferred embodiment of the invention, the punching tool is thus configured in such a manner that it is capable of punching one or more holes in a sheet extending essentially in a plane in parallel with the essentially plane surface of the housing of the perforator.

In this context, the punching tools are conveniently each separately configured as a rod with a longitudinal axis and a first end on which a cutter blade is configured which is capable of rupturing the sheet when the rod is shifted along its longitudinal axis and through the sheet.

According to one embodiment which will be compatible with many known toy building sets, each coupling stud and each punching tool is configured to be essentially circular cylindrical to the effect that the centre axis of each punching tool constitutes the longitudinal axis thereof, and wherein one of the complementary coupling means is arranged such that the centre axis of the coupling stud coincides with the centre axis of one of the punching tools.

In this context the diameter of the punching tool conveniently corresponds to the corresponding diameter of the coupling stud, since a very accurate positioning of the sheet on the coupling studs is hereby accomplished.

To that end, the housing of the perforator may comprise an operating handle configured on the opposite side of the housing relative to the plane surface, and said operating handle being configured such that, when pressure is applied onto it in a direction towards the housing, one or more punching tools is/are activated for punching one or more holes in the sheet. Thereby the force to be applied to the operating handle will act essentially in parallel with the centre axis of the coupling stud to the effect that the risk of the perforator disengaging from the coupling studs during the punching effect.

Moreover, the housing of the perforator may comprise a relatively thin slot for receiving a sheet, and said slot extends into the housing essentially in parallel with the essentially plane surface to the effect that it is ensured that eg a child is not hurt by its finger or other being inserted below the punching tools during the punching process.

According to a particularly preferred embodiment, the perforator comprises at least four punching tools that are configured in a square pattern at a mutual distance corresponding to the mutually fixed distance between two adjacent coupling studs on the building element.

The invention also relates to a perforator as such, said perforator comprising a housing, wherein means are configured for punching material from a sheet element configured from a thin material, such as a sheet of eg paper, plastics or fabric, in such a manner that the perforator is capable of punching a hole in the sheet. The housing according to the invention having, in this context, an essentially plane surface, wherein at least two indentations are configured next to each other, said indentations being configured such that they are capable of engaging with and receiving a corresponding number of coupling studs that are configured such that they extend from an essentially plane surface on another element, such as a building element for a toy building set, and the coupling studs having an essentially circular cylindrical surface with a centre and a diameter of 4.8 mm and are configured such that the distance between two adjacent coupling studs is 8 mm to the effect that the distance between the circular cylindrical surfaces on two adjacent coupling studs is 3.2 mm, this perforator is suitable in particular for use in connection with a known toy building set.

The same applies in the context of another known toy building set if the perforator is configured in the same way, but wherein the coupling studs have an essentially circular cylindrical surface with a centre and a diameter of 9.6 mm instead and are configured such that the distance between two adjacent coupling studs is 16 mm to the effect that the distance between the circular cylindrical surfaces of two adjacent coupling studs is 6.4 mm.

EMBODIMENT OF THE INVENTION

Thus, FIG. 1 shows a perforator 1 according to the present invention, said perforator 1 comprising a housing 2, wherein a slot 3 is configured wherein a sheet of a (not shown) thin material, such as paper, plastics, fabric, or other material can be introduced, and an operating handle 4 which, when operated, is pressed downwards in a direction towards the housing 2 of the perforator, and thereby activates a number of punching tools that are driven to shift transversally of the slot 3, whereby the punching tools are driven through the not shown sheet of a thin material and produce one or more holes in the paper depending on the number and configuration of the punching tools.

The punching tool shown in FIG. 1 having several separate punching tools, it further comprises a second operating tool 5 which is used to change how many of the punching tools that are activated at the same time when the operating handle 4 is depressed.

According to one embodiment of the invention, it is part of a toy building system or a toy building set, by which is intended a number of building elements or building blocks of the type which is shown eg in FIG. 2 showing a building element 6 having a surface 7 which is provided with a total of four coupling studs 8. It will thereby be obvious to the person skilled in the art that the perforator can be a separate product suitable for use in existing products or as a tool sold along with a number of building elements.

Moreover, it will be obvious to the person skilled in the art that the building element shown in FIG. 1 is one of many embodiments of building elements, and that the invention can be used in connection with building elements having more or fewer coupling studs 8 than is shown in FIG. 1 and optionally having studs of other configurations or mutual distances than the one shown in FIG. 1.

The perforator 1 as shown being provided with a number of indentations 9 on its essentially plane bottom face, said indentations being configured such that they each form a number of coupling means that are complementary relative to the coupling studs 8 on the building element 6, it is possible to mount the perforator on a building element of a toy building set, if that building element is provided with coupling studs having the same shape and mutual distance as the one shown in FIG. 2. If the perforator 1 is mounted eg on a building element or a building plate having many more coupling studs 8 than the building element 6 shown in FIG. 2, such building plate will be able to serve as a kind of boring template for accurate mutual positioning of several groups of holes on a sheet.

Now, FIG. 3 shows a part of the same perforator 1 as the one shown in its entirety in FIG. 1. Herein it is primarily the frontmost end of the perforator that is shown, in a sectional view, wherein the sectional plane is arranged in parallel with and slightly displaced relative to the plane of symmetry of the housing 2. As will appear, the operating handle 4 is journalled, relative to the housing 2, about a shaft 11, and upon depression of the operating handle 4 in the direction of the housing 2, the operating handle 4 will press the piston 12 downwards towards a selector disc 13 that subsequently presses one or more of the punching tools 14 downwards transversally to the slot 3 to the effect that the punching tools 14 are, in a known manner, pressed through a not shown sheet that has been shifted into the slot 3 and extends below the punching tools.

According to an embodiment of the invention, it is possible to vary the number of punching tools 14 that are activated simultaneously by depression of the operating handle 4. Thus, FIGS. 4 and 5 will show the frontmost part of the perforator shown in FIG. 1, where the upper shell that constitutes a part of the housing 2 in FIG. 1 has been removed in FIG. 4, and wherein the operating handle 4 and the second operating handle 5 have moreover been removed in FIG. 5.

Herein, it will thus appear that the second operating handle 5 is, via the piston 12, connected to a hole selector 15, herein shown in the form of a circular disc with a number of cut-outs that are configured such that, when the hole selector, when positioned as shown in FIG. 5, is pressed downwards towards the punching tools 14, all four punching tools 14 will be pressed simultaneously down towards the slot 3, and in this manner all four punching tools are activated to punch a hole in the sheet.

If the hole selector 15 is subsequently rotated a small distance in the counter-clockwise direction, the two pointers 16 on the hole selector 15 will be precisely clear of two of the four punching tools 14, and if the hole selector is rotated a further distance in the counter-clockwise direction, it will further be capable of occupying a position in which only one of the four punching tools is activated when the operating handle 4 is depressed.

It will be obvious to the person skilled in the art that embodiments of perforators may be suggested that are different from the one described above and shown in the drawing. Thus, the principle of the invention can also be used in an embodiment where the perforator is configured as a pair of thongs having two operating handles that can be pressed towards each other, and more or fewer punching tools than the four provided herein can be provided.
